Transplanted Testicles Will Always Make the Donor’s Sperm

May 7, 2018

(The Verge) – A veteran of the US Armed Forces has a new penis and scrotum after the most extensive penis transplant yet, Johns Hopkins Hospital announced this week. Not included in the transplant? Testicles — because the testicles would continue to make the donor’s sperm in the transplant recipient’s body. The patient, who asked Johns Hopkins not to reveal his name, suffered a devastating injury to his penis, testicles, part of his lower abdomen, and his legs in Afghanistan when an improvised explosive device blew up, TheNew York Times reports.
